To all whom it may (JOIN/WW1.

Be it known that l, Josnrrr KAUFMAN, a citizen of the Republic of Russia, and a resident of New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Locks, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a class of locking devices.

My invention has for its object primarily to provide a lock designed to be employed on the doors or the like of buildings and elsewhere whereby surreptitious access through the entrance when locked will be prevented, and which is of a form serving to prevent the door or other closure of the entrance from being jimmied or pried open by the methods usually employed to accomplish such purposes. The invention consists essentially of a casing adapted to be applied on a door, and in the casing is a bolt which is movable inwardly and outwardly toward and from the jamb of the door. Adapted to be applied on the jamb of the door in opposition to the bolt may be one or a number of orificed elements, and on the bolt exteriorly of the casing may be a like number of gripping elements for removably engaging the orificed elements when the bolt is moved inwardly of the casing following the outward movement of the bolt. The associate parts of the device as well as the door will then be releasably locked.

Another object of the invention is to provide in the casing mechanism which is operable for causing the bolt to be moved outwardly and inwardly of the casing: and a further object of the invention is to provide a lock of a simple, eflicientand durable construction which may be made in any desired shape and size.

With these and other objects in view the invention will be hereinafter more'fully described with reference to the accompanying drawings forming a part of this specification in which similar characters of reference indicate c'oresponding parts in all the views, andwill then be pointed out in the claims at the end ofthe description.

In drawings, Figure 1 a view show Specification of Letters Patent.

Application filed December 14, 1918. Serial No. 266,705.

ing an elevation of a door with one form of lock embodying my invention applied thereon.

Fig. 2 is an enlarged fragmentary detail sectional view taken on the line 22 of Fig. 1.

Fig. 3 is an enlarged plan, partly in section, showing the parts of the lock in locked positions.

Fig. 4 is an enlarged plan, also partly in section, showing the parts of the look when in unlocked positions, and

Fig. 5 is an enlarged perspective view of the lock with the rear wall of the casing removed.

The device or lock has a casing 10 which may be of any suitable shape and size, though the casing is preferably formed to provide a front wall 11, rear wall 12, end wall 13, and a side wall 141, all of which may be made of metal or other material. Through the front wall and rear wall of the casing may be a number of registered holes, as 15, for reception of screws or bolts whereby the casing may be fastened on the door, as 16. or the like of a building and elsewhere, the casing being applied to the door in proximity as well as in oposition to the door jamb, as 17 In the central part of the end wall 13 of the casing is an opening 18, and at the ends of this wall, besides being spaced from opposite parts of the opening 18 may be two holes or openings 19 and 20.

Movable inwardly and outwardly of the casing 10 through the opening 18 is a bolt 21. This bolt has a stem 22 of a shape which preferably conforms to the shape of the opening 18 as well as being of a size to movably fit closely the opening, and the bolt may be of a length so that one of its ends extend into the casing approximately to the center thereof, while the second end of the bolt protrudes some distance beyond the end wall 13 of the casing. The end of the bolt interiorly of the casing may be cut away or reduced in size, as at 23, and on the end of the bolt exteriorly of the casing is a head, as 24:, having one or a number of gripping elements, as 25 and 26.

The head 24 is preferably in the form of a bar provided on the second end of the stem 22 of the bolt so that the bar is disposed transversely of the stem, besides being disposed lengthwise with respect to the end wall of the casing. When the stem of the bolt 21 is moved outwardly and inwardly of the casing the bar or head 2-1 will also be moved in similar directions in opposed relation to the end wall of the casing, and this bar is of a length so that its ends extend over the holes 19 and 20 of the end wall oi" the casing. The gripping elements 25 and 26 are preferably in the form of lugs which are provided on parts of the bar 2-4: in opposition to the holes 19 and 20 of the end wall 13 of the casing as well as being disposed toward the holes, and these gripping elements or lugs are of sizes for being freely admitted into and removed from the holes when the bar 24 and the stem 22 ot' the bolt 21 are accordingly moved. Furthermore, the lugs 25 and 26 are of lengths so that when the stem of the bolt is moved its maximum distance outwardly of the casing 10 the free ends of the lugs will be spaced a predetermined distance from the end wall of the casing.

The lock also has an orificed element, as 27, which cooperates with the bolt 21 to enable the door or the like to be locked against being surreptitiously opened. The orifieed element 27 is composed preferably of a plate which may be substantially L- shaped to provide an arm 29 with a second arm 30 which is disposed right-angularly from the arm This L-shaped plate is adapted to be arranged on the door aiub 17 so that the arm of the plate will be in opposition to the casing, while the arm 30 extends forwardly with respect to the end "all 13 of the casing, and through these plates may be a number of holes, as shown, for passage of screws or bolts whereby the orificed element may be fastened on the Jamb of the door. Protruding angularly from the arm 30 at its uncture with the arm 29 of the plate or element 27 may be one or a number of eyes or orificed lugs, as 31 and The apertures of these eyes are of proper size and spaced apart at distances to freely receive the gripping elements or lugs 25 and 26, and the eyes are also of such size as to be readily accommodated between the free ends of the lugs and the end wall 13 of the casing 10. Moreover, the casing 10 and the element 27 are arranged on the door and on the jamb so that when the bolt 21 is guided its maximum distance outwardly of the cas- 111g lOthe eyes 31 and 32 of. the element '27 will pass between the free ends of the lugs- 25 and 26 of the bolt 21 and the end wall 13 of the casing when the door is shut. and the casing 10 and element 27 are relatively so arranged that the apertures of the we; 3] and 32 will be in register with the holes 19 and 200i the end wall of the casing. when the door is shut. The gripping elements or lugs 25 and 26 of the bolt 21 will thereby pass through the eyes 31 and 32 into the holes 19 and 20 when the bolt is reversely guided inwardly of the casing 10. The bolt 21 will thereby be locked to the element 27, and to enable the bolt to be guided outwardly and inwardly of the casing, I provide in the easing a mechanism, as 33.

The mechanism 33 may be of any suitable type, though this mechanism preferably consists of a flat finger or extension, as 3st, which is provided on the reduced part 23 of the stem 22 of the bolt 21. The flat finger 3t may be angular in shape, as shown, besides being disposed so as to be movable interior] y of the casing in contact with its frontwall 11, and this finger may be of a length so that its free end is in spaced proximity to the part of the casing 10 which is opposite to the end wall 13 of the casing. Protruding interiorly of the casing 10 from its front wall may be two spaced short lugs 35 and 36 between which the finger 31 is movable for causing the finger and the bolt 21 to be ac eurately guided during their movements outwardly and inwardly of the casing 10. In one oi the edges of the finger 34 of the bolt 21 at the free end of the finger is anotch 37, and protruding toward the rear wall of the casing from the finger at one side of the notch 37 is a short lug, as 38, while protruding in a similar direction from the finger at the other side of the notch is a second lug Also projecting toward the rear wall of the casing from the finger 34 at its juncture with the stem 22 of the bolt 21 is a short pin 4:0, and extendingin a. like direction from the finger at its elbow is another pin i1. On the pin 10 of the finger 34: of the bolt is pivotally held one end of a lever 42 which is of a. width as wellas being arranged to allow of being moved back and forth crosswise of the finger, and this lever is of a length to extend to the notch 37 of the finger. One of the edges of the lever 42 adjacent to its second end is notched, at 413, to provide a somewhat rounded head or extension, as H. which is movably disposed in the notch 37 of the finger 3 1 of the bolt, and in the notch 4:3 of this lever protrudes the lug 39 of the finger to limit the movement of the lever in a direction toward the notch 37. To the pivoted end of the lever 12 is secured one end of a spring, as 15, having its second end invmovable contact with the pin '11 of the finger 34- of the bolt, and this spring normally serves to yieldingly force the lever 42 so that its head -14 movably extends normally outwardly of the notch 37 of the finger 34:. R0- tatable in an opening in the front wall of the casing 10 of the lock is a shank, est- L6,

gNlllCll ot' a length so that one of its ends extends beyond the front wall of the casing and so thatits second endeXtends-interiorly of the casing, although this shank maybe of a length whereby its second end may be retatably disposed through an opening in the rear wall of the casing to allow any well known or preferred type of tumbler barrel for looks to be applied to the shank. On the end of the shank 46 projecting beyond the front wall of the casing may be a handle, as 47, to allow the lock to be manually operated, and on the shank interiorly of the casing is a key, as 48, to cause the mechanism to operate. The key 48 is preferably in the form of a cam havinga ringlike body 49 which is fixed on the shank 46. Projecting from opposite parts of the ring 49 are two oppositely disposed lugs or fingers 50 and 51, and this key or cam is arranged so that one of the fingers will rotatably move in the notch 37 of the finger 34 of the bolt 21 for contacting with the head 44 of the finger 42 when the cam is rotatably' swung accordingly.

The lock is operated following its parts being applied on the door and jamb, as above described, by turning the handle 47 and its shank 46 to swing the key or cam 48 so that one of its fingers 50 or 51 will contact with the head 44 of the lever 42 to cause the lever to be swung against the tension of the spring 45 so that its head will be moved in a direction crosswise of the lever from between the lugs 38 and 39 of the lever. The finger of the key 48 will then contact with the lug 39 of the lever, and with the continued rotary movement of the key the finger 34 and its associate bolt 21 will be swung outwardly of the casing 10 of the look through the opening 18. The head 24 with the gripping elements or lugs 25 and 26 will then be similarly moved in spaced relation to the end plate 13 of the casing 10, and with the closing of thedoor the eyes 31 and 32 of the element 27 will pass between the lugs 25 and 26 of the head 24 and the end plate of the casing. To look the door following this movement of the bolt outwardly of the easing 10 the handle 47 is reversely rotated, and in turn the finger of the key 48 which may be disposed in the notch 37 of the bolt 21 will contact with the lug 38 of the finger 34 of the bolt. The bolt will then be guided inwardly of the casing for causing the lugs 25 and 26 to passthrough the eyes 31 and 32 of the orificed element 27 as well as causing these lugs to be seated in the openings 19 and 20 of the end wall 13 of the casing. The door will thereby be locked against being jimmied or surreptitiously opened by the methods commonly used.

In the foregoing description, I have embodied the preferred form of my invention,

but I do not wish to be understood as limiting myself thereto, as I am aware that modi- "fications may be made therein without departing from the principle or sacrificin any of the advantages of this invention; there fore I reserve to myself the right to make such changes as fairly fall within the scope thereof.
